Box-MAKI MACHINE.-

SPECIFICATION forming part of' Letters Patent No. 478,456, dated July 5,1892. I Application filed November 28, 1891 Serial No. 413.433. (Nomodel.)

To all whom itmayboncern:

Be it known that I, JOSEPH CAMERON Mc- EWEN, acitizen of the UnitedStates, residing at Lochloosa, in the county of Alachua and State ofFlorida, have invented certain new and useful ImprovementsinBox-MakingMachines; and I do declare the following to be a full, clear, and exactdescription of the in-.

object the providing of a machine for holding in proper position theparts" of the box during the process of assembling, and nailing. Tothese ends and to such others as the in "vention may pertain the sameconsists in the 'pecullar construction and in the novel combination,arrangement, and adaptation of parts, all as more fully hereinafterdescribed, shown in the accompanying drawings, and thenspecifically-defined in the appended claims. V

In the accompanying drawings, which form a part of this specification,and in which like of heavy timbers and should be ofconven-- ient heightand of a length andwidth to adapt it to use in the construction, ofboxes of the size which itnn'ay be proposed to manufacture. The upperface of the table B of the machine is provided with a series oftransverse recesses or spaces 0 to receive the lower crate to beconstructed. Rising from the table B at its rear edge arethe uprights EE, and supported upon these uprights is a shelf F, which is providedwith a raised strip F, extending around its outer edges. is designed asa receptacle for} nails, so that the nail-supply may at all timesybewithin convenient reach of the operator.

with a series of notches F which serve to receive the edges of'thelbox-heads D and hold as shown. v

G is a rock-shaft, which is journaled within suitable bearings at therear of the frame A and provided at one of its ends with an operatinglever or handle G.

are provided at their free ends with presserposition in themachine willpress against the faces of the heads and hold the same securely inposition for nailing, as shown clearly in Fig. 1 of the drawings.

In order to insure a firm pressure of the blocks H against thebox-heads, a pin or lug I is provided upon the rock-shaft at a pointnear one of its ends, and when the shaft (which is longitudinallymovable in its bearings, as shown) is'turned so as to cause the blocks Hto contact with thebox-heads this lug engages an inclined surface H uponthe frame A and the shaft is thus forced along in a direction which willtend to carryv the blocks H into close contact with the boxheads, aswill be readily understood. In order that the pressure-blocksmay-beautomatically thrown out of contact with the box-heads when thelever G is thrown upward, I provide a block J, which is secured to theend of the upright portion or shelf F. This strip or block is cut awayat its forward end, as shown, said cut-away portion forming an inclinedsurface against which the lever G contacts when thrown upward. Thiscontact of the edges of the ends or heads D of the box or.

This shelf The front edge of the shelf F is provided the same steadilyin place when being nailed,

This rock-shaft is provided with a series of arms H H, which blocks H,which when the boxrheads are in leverwith the block will have the,effect of throwing the lever outward, carrying with it the shaft G andmoving the presser-blocks out of contact with the box-heads.

The operation of the machine is simple and will be readily understood.The shaft G is thrown upward and the box or crate headsp are placed inposition within.the recesses C, with the rear edges inserted within thenotches in the shelf F. The operating-handle is then thrown forward, asshown in Fig.1, and the pre'sser-blocks are forced against the faces ofthe box-heads, which are thus securely held in position for receivingthe slats or sides of the box. When one of the sides of the box has beennailed the lever is raised or thrown back, thus releasing thepresserblocks from'engagement with the heads D.

While I have shown a machine adapted for use in the construction oforange-boxes in which three heads are used,- it is at once evidentthatthe principle involved is equally well adapted for use in themanufacture of any of the various forms of boxes.

Having thusdescribed my invention, what I claim to be new, and desire tosecure by Letters Patent, is

1. The combination of the main frame hav ing recesses to receive thebottom and rear edges of the box-heads, a rock-shaftjournaled to therear of the frame, the arms H attached to the shaft and carryingpresserheads, as described, and the operating handle 0r lever foractuating the shaft, substantially as and for the purpose described.

2. The herein-described machine for use i in the manufacture of boxes orcrates, the

same comprising the main frame having recesses to receive the loweredges of the boxheads, the shelf to the rear of the frame andsupportedupon uprights risingfrom theframe,

the rock-shaft j ournaled to the rear portion of the frame andlongitudinally movable within its bearings, the arms attached to theshaft,

the presser-blockscarried by the arms-,- the lug Inpon theshaftandengaging an inclined surface upon the frame, and the lever for actuatingthe shaft, substantially as and for the.

purpose described.

In testimony whereof I affix my signature in.
